If your MYOB accounting data is offline you will have to add and update your organisation to Calxa using the Calxa desktop app.
Once your organisation has been added/updated sign in to the Calxa online app to continue working there.
Working in the online app will allow you to take advantage of all the new features and benefits of the app (excluding automated organisation updates).
